Advanced Applications and Novel Technologies of Positron Annihilation

Dear Colleagues,

Positron Annihilation Technique (PAT) is an unique nuclear physics technique that can provide information about the microstructure in atomic scale, electron momentum distribution and defect state, and so on. It has been developed and widely applied for materials research in the past few decades. A lot of studies have focused on discovering and observing phenomena, improving experimental techniques, and proposing various theoretical models for tentative descriptions. So far, it has entered the stage of devoting to quantitative or semi-quantitative theoretical on physical processes and experimental research in the field of material science (such as solid-state physics, semiconductor, metal, polymer, surface physics, and superconducting physics), biology, chemistry and medicine. In special materials science research, positrons play an important role in atomic-level defect determination/identification and phase transition research. The development of sub-nanosecond nuclear electronics technology, submiradian-angle correlation measurement technology and high-energy resolution semiconductor detectors can finely measure the annihilation characteristics of positrons, so that the research and application of novel positron annihilation technology have been rapidly developed.

This Special Issue, “Advances Technologies and Applications of Novel Positron Annihilation”, will be a collection of full papers, short communications and review papers focusing on recent progress in the field of fundamental aspects, applications and devices based on them. The goal of the Special Issue is to provide a platform for positron researchers from all over the world to present their latest research results and new ideas.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
